• I've been seeing quite a lot of discussions of web design style lately. Compare the emerging style of early web design with the polished Web2.0 Style. Even newer styles, such as Grunge and Hand-Drawn use the techniques of modern web design while breaking from the Web 2.0 aesthetic.
• Rich Programmer Food: On compilers and the most important class for computer scientists.
• An article on "Turing Tar Pits" and how programmers make things hard for themselves.
• How to teach yourself programming in ten years.
• 10 Python Quirks: Read this if you're a Python programmer. Did you know all of those? (I didn't.)
• An anecdote about teaching children programming.
• Big Red Angry Text: On CSS styles for debugging

• Post-It Note Art: Completely amazing!
• On why "don't talk to strangers" is "just about the worst possible advice you can give a child".
• An article on the Naked Rambler, who in January was free for several steps before being arrested again for his persistent nudity. *facepalm* How should society deal with such people? And should (yes, I mean that in the moral sense) the Naked Rambler just wrap / shut up and conform?
• An anecdote on parenting, food, and vegetarianism.
• The website for Urville, a fictional city created by a savant who now makes a living by imagining / drawing / writing about / talking about said fictional city. Also a particularly good example of (what I'd refer to as) 90's Crazy web design style.
• A recipe for Pan Seared Salmon with Avocado Remoulade
• A video on turning a sphere inside-out. Nifty. Watch if you're interested in topology / are wondering what the heck "topology" means.
• On creating a warning marker to last for 10,000 years.
• Why Starbucks actually helps local coffee shops.

• Flexible syntax makes regular expressions a bit easier
• Flexible syntax makes "golfing" your code (doing it in fewest keystrokes) easier

• Anything having to do with objects
• Anything having to do with references
• Anything to do with variable names (sigils, magic variables, etc.)
• High levels of kludginess in the core features

• You need it for a job
• You're a Level 20 Unix Mage
• You hate maintenance programmers with a burning fiery passion
• You're a sado-masochist who is still working on convincing your firm to program entirely in INTERCAL

• I went to Wellesley for that Social Psych. class; still don't know if I'll get into that.
• In Principles of Engineering, we started on the first lab, building USB based circuits with a PIC micro-controller (PIC18F2455) and frobbing a program written in quasi-assembly (so far we've just programmed it to make an LED blink on and off, but still, I get to learn some assembly code).
• Also, I bought Star Fox: Assault (because, dude, Star Fox, although that review has it right; it adds nothing revolutionary to the series).
